PR-645: 2012 Orchardgrass Report
David Ditsch, Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Nov. 26, 2012 (New)
Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is well-adapted to Kentucky conditions. This grass is used for pasture, hay, green chop, and silage, but it requires better management than tall fescue for greater yields, higher quality, and longer stand life. It produces an open, bunch-type sod, making it compatible with alfalfa or red clover as a pasture and hay crop or as habitat for wildlife.
PR-644: 2012 Red and White Clover Report
David Ditsch, Garry Lacefield, Gene Olson, Ray Smith | Nov. 26, 2012 (New)
Red clover (Trifolium pratense L.) is a high-quality, short-lived, perennial legume used in mixed or pure stands for pasture, hay, silage, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. Stands of improved varieties generally are productive for 2.5 to 3 years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, yield, and animal acceptance.
PR-643: 2012 Alfalfa Report
Garry Lacefield, Gene Olson, Ray Smith | Nov. 26, 2012 (New)
Alfalfa (Medicago sativa) has historically been the highest-yielding, highest-quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Choosing a good variety is a key step in establishing a stand of alfalfa. The choice of variety can impact yield, thickness of stand, and persistence.
PR-642: 2012 Kentucky Hybrid Corn Performance Test
Bill Bruening, Jessica Cole, Ron Curd, Chad Lee, Bill Pearce | Nov. 12, 2012 (New)
The objective of the Kentucky Hybrid Corn Performance Test is to provide performance estimates of hybrid seed corn sold in Kentucky. The test has been conducted in an unbiased manner according to accepted agronomic practices.
HENV-505: Impacts of Additives on Septic System Performance
Mark Coyne, Brad Lee | Sep. 19, 2012 (New)
Septic system additive vendors often market their products as necessities that improve septic system performance or repair failing systems. Rather than address specific products, this publication examines general categories of these additives. This publication also describes the treatment functions of septic systems and the available scientific data regarding the effectiveness of septic system additives.
HENV-503: Septic Tanks: The Primary Treatment Device of Septic Systems
Brad Lee | Sep. 19, 2012 (New)
Septic tanks play an essential role in effectively treating wastewater in areas without municipal sewage treatment. Homeowners often assume that the septic tank in their backyard is their septic system. Actually, the tank is merely the first of a series of components that make up a well-designed septic system.
HENV-507: Flood Conditions and Your Septic System
Brad Lee | Sep. 19, 2012 (New)
The most common septic systems used in the United States employ soil treatment area to treat and disperse wastewater into the environment. The soil treatment area consists of a network of perforated pipes within gravel-filled trenches. Under normal environmental conditions, well designed and managed septic systems work very well at dispersing wastewater and removing pathogens from the wastewater before they reach groundwater or surface waters.
HENV-501: Septic System Maintenance: Care and Feeding of Your System
Brad Lee | Sep. 19, 2012 (New)
This publication provides homeowners with a basic introduction to septic systems by explaining how septic systems function and suggesting ways to better maintain systems and increase their longevity.
HENV-504: Importance of Wastewater Biological Oxygen Demand in Septic Systems
Mark Coyne, Brad Lee | Sep. 19, 2012 (New)
A high BOD value means potential septic system problems for homeowners; a low BOD means fewer problems for homeowners. This publication describes the environmental impacts of BOD, shows how BOD is distributed in septic systems, and describes remediation strategies for excess BOD.
HENV-502: Septic System Failure and Environmental Impacts
Brad Lee | Sep. 19, 2012 (New)
More than one-third of new homes and over half of the mobile homes in the U.S. depend on septic systems. Here in Kentucky, approximately 40 percent of the homes have septic systems. This is common in the southeast, where there are more septic systems per capita than any other region of the country.
